襯氟止回閥又稱逆止閥。這種類型的閥門的作用是只允許介質(zhì)向一個(gè)方向流動(dòng)，而且阻止方向流動(dòng)。通常這種閥門是自動(dòng)工作的，在一個(gè)方向流動(dòng)的流體壓力作用下，閥瓣打開；流體反方向流動(dòng)時(shí)，由流體壓力和閥瓣的自重合閥瓣作用于閥座，從而切斷流動(dòng)。中文名襯氟止回閥外文名Fluorine-linedcheckvalve又稱逆止閥作用只允許介質(zhì)向一個(gè)方向流動(dòng)工作自動(dòng)工作目錄1簡(jiǎn)介2襯氟止回閥結(jié)構(gòu)分類3襯氟止回閥主要襯里4襯氟止回閥作用原理和結(jié)構(gòu)5性能參數(shù)6襯氟止回閥主要零部件材料襯氟止回閥簡(jiǎn)介編輯襯氟止回閥包括旋啟式止回閥和升降式止回閥。旋啟式止回閥有一介鉸鏈機(jī)構(gòu)，還有一個(gè)像門一樣的閥瓣自由地靠在傾斜的閥座表面上。為了確保閥瓣每次都能到達(dá)閥座面的合適位置，閥瓣設(shè)計(jì)在鉸鏈機(jī)構(gòu)，以便閥瓣具有足夠有旋啟空間，并使閥瓣真正的、范圍廣的與閥座接觸。閥瓣可以全部用金屬制成，也可以在金屬上鑲嵌皮革、橡膠、或者采用合成覆蓋面，這取決于使用性能的要求。旋啟式止回閥在完全打開的狀況***體壓力幾乎不受阻礙，因此通過閥門的壓力降相對(duì)較小。升降式止回閥的閥瓣座落位于閥體上閥座密封面上。此閥門除了閥瓣可以自由地升降之外，其余部分如同截止閥一樣。泰州對(duì)夾單瓣旋啟式止回閥河北鼎力閥門是一家專門生產(chǎn)制造銷售止回閥的公司，主要有雙瓣旋啟式止回閥，耐腐蝕緩沖止回閥等。</p><div
